I’d just like to drop a fuck you in here to oscillators. Especially ones that worked absolutely fine yesterday but not today  >:(

Need that bloody function generator to check the phase shifts and loop gain. But nope thanks UPS for fucking that up.

And there was another brand I can't remember now with a square of skin big enough to identify as pig, hairs included. *blerk*

What? You asked for dead pig, you got dead pig - where's the problem.  :)

At least it wasn't chittlin's.




It was supposed to be a chicken pot pie.  :P

At least it wasn't rabbit.  >:D

OK, I think you might just have a legitimate gripe there.  :)
Anybody got a syringe I can use to squeeze the magic smoke back into this?

I'm a firm believer in doing burn-in's after a repair, especially on vintage equipment. Case in point: The Type 3A74 Vertical plug-in after about 2 hours started going unstable on the channel 1 trigger again. And eventually would not trigger at all. So back on the plug-in extension.

See schematic. The trigger signal dropped out at the emitter/base junction of Q503 and Q504. Turns out R502 (160K) was drifting high and a shot of freeze spray restored SOME trigger. So it was replaced. Now had trigger....sometimes. That turned out to be Channel 1 trigger DC level pot bottomed out. I never touched it. Phantom Gorilla's. Adjusted pot and now trigger is absolutely stable. And just for giggles I re-installed the old Q504 and yep, it's bad. So there's an NTE160 in it's place. 

If it passes a few burn-in's this plug-in will be complete.

This weeks installment of toolpr0n for you: connector contact insertion and removal tools (a small assortment of)
[attach=3]
[attach=2]
[attach=1]
Lower part on the first pic are all Mil-listed, upper part around half. This is a field which is likely to rub the inadequacy of one's kit right under your nose. Wayyyy to go until I am able to handle just all of those connectors which I have already encountered, and just more so if I include all those which I am likely to encounter.

This is an area where the hunt for completeness will kill you. I admire the effort.

And here I thought I was a crazy man for owning 6 torque wrenches.

What's the trick to get a module out of the frame if the handle is broken?
I did use the following trick, which is applicable if the remaining part of the lever is visible and functional:
<snip>

No such luck here.. But, it nevertheless is inspiring.

Just as we were mentioning it, I had a go at trying to use it, mostly for fun, not expecting any sensible results. And all of a sudden it starts to work! I trust it as long as a 200dlb gorilla can throw it, but it helped me verify my project, since results correlate. Hey ho.

Disgusting, but at least not as bad as shot in wild fowl dishes. Especially since that thrice-damned steel shot. Broke a tooth on a single #7 or #8 pellet in a partridge confit.

There's really no excuse for this nowadays is there? Now they're using steel shot it's easy enough to detect electrically. Most commercial food factories have magnetic/inductive sensing to make sure that a nut or washer off the machinery hasn't made its way into the product. Surely that can be repurposed for game?

Having had to professionally purchase some of that tackle in the past I shudder at what that tool case represents in "new replacement cost" real money.

Indeed. And aquisition was not exactly free. It is about 1/3 regular purchases, 1/3 surplus and ebay and the remainder found/migrated/contributed by others.

Huh. Where is the craziness here if the coaxial connectors already make at least  4 different ones necessary (N/SMA(steel)/SMA/SMC)? And I would not want to be without a spare for SMA.
(Thanks to <Kosmic> this is now fulfilled with a better one than before)

If you buy a game fowl, there has to be shot in it, somewhere vital.

Yeeowwch! Nice collection of roach clips; you've got one for every popular variety and some of the more esoteric buds, I'll wager.  :-DD

No, seriously... that's a habit that'll eat you out of grocery money almost as fast as photography... Can't count how many times I've wished for ones not in my little Cheap China kit, or had to spend umpty minutes bending/Dremeling a bit of sheet-metal or tubing to make "something that works" without buggering up a connector too bad.

More power tooya, my friend!  :-+

If you're feeling really generous to the community... some close-up pics with mic'd-out dimensions would be a huge contribution. Even if it's just a few of the ones you've used most.

Cheers,

Well, I was all set up to join the discord session last night and guess what, I fell asleep. It was so bloody hot last night in my small lab that I just dropped off to sleep. I had 3 fans switched on to cool the place down and still it was 33C in here  :wtf:. I'm guessing that the body just shut itself down to. Did I miss anything good?  :-DD :-DD

In the chat were some people, e.g. bd139, but in the audio channel there were only four of us:
Saskia, ch_scr, BU508A and AVGresponding. But a lot of people left early, probably for being tired.

Perhaps next discord session, if the heat stays away.

I was urgently and intensively occupied otherwise. Will attend next time, probably.

Sure, there's no factory but the implicit point was "Why doesn't some repurpose that technology for game dealers/butchers?".
